Orb of Harmony

Zenyatta casts an orb over the shoulder of a targeted ally. So long as Zenyatta maintains line of sight, the orb slowly restores health to his ally. Only one ally can receive the orb’s benefit at a time.

Transcendence (Ultimate)

Zenyatta enters a state of heightened existence for a short period of time. While transcendent, Zenyatta cannot use abilities or weapons, but is immune to damage and automatically restores his health and that of nearby allies.
